Does it make a difference whether you put synthetic motor oil or non synthetic to your car?

Will putting one vs the other do any harm or damage to your car? The reason I ask this is because when I get an oil change for my car, I always go to the same place where they put the same kind of motor oil and I'm afraid to put the wrong kind for fear that it will ruin my car. I drive an old pathfinder of over 100,000 miles.Does it make a difference whether you put synthetic motor oil or non synthetic to your car?
Synthetic oils provide the best protection at all temperatures and through a longer time period. If Iwere yoou, I would have someone evaluate your engine for the presence of sludge (caused by conventional oil), have it removed, and switch to Mobil One. You have nothing to lose and everything to gain. More engines break down from poor lubrication and excess heat than anything else, (except broken timing belts). The higher detergent factors will continue to clean your engine as you drive it. Be sure that you are using a high quality fuel (like Mobil) with high detergency. It keeps things clean inside and helps prevent formation of sludge. Keep your engine bay clean with frequent shampooing. This prevents formation of ';hot';spots. You can check the thing yourself, by removing your oil filler cap and turning it over. Any debris found here will be what the entire inside of your engine will look like. Be sure that your PCV and PCV hoses are clean and working properly, as well. Good Luck!Does it make a difference whether you put synthetic motor oil or non synthetic to your car?
supposedly synthetic oils are better for higher mileage vehicles, but I still use regular motor oil in my car, which has over 120k on it
With your vehicle, stick to regular oil. Syntheitc has higher tolerance for heat, and breakdown, but it's much more expensive. Regular oil is fine.
your motor life will be increased by using synthetic oil.


However at the milage you have stick with what you have been using to switch now is unneeded. Just make sure when you get an oil change at the local oil place they are changing your filter also, more often then not they dont witch is makes the oil change pointless. If you even get a new car switch it over to synthetic after the 1st 3k miles the dif in price vs wear and tear damage is worth evey penny.
I would stay with the regular oil. Too late to justify the extra expense on a car with high mileage. Changing can even cause problems on old vehicles. Synthetic oil has been reported to damage the seals and cause oil leaks.





Hope this helps
ok synthetic oil is better because it is thicker , and in the cold it has a better start up. thATs why in the winter if its going to be below zero make sure its changed. but to answer ur question its ur preference on what u like but if u have somebody do it for u u never know if there even changing it for u. i pput max life its for cars seventy thousand and over. but synthetic is goo but expensive ok bye.
